1、网页查看

2、有道翻译简单实现源码

import requests#请求头#headers不能只有一个User-Agent，因为有道翻译是有一定的反扒机制的，所以我们直接全部带上headers = {    "Accept": "application/json, text/javascript, */*; q=0.01",    "Accept-Encoding": "gzip, deflate",    "Accept-Language": "zh-CN,zh;q=0.9",    "Connection": "keep-alive",    "Content-Length": "244",    "Content-Type": "application/x-www-form-urlencoded; charset=UTF-8",    "Cookie": "OUTFOX_SEARCH_USER_ID=-1506602845@10.169.0.82; JSESSIONID=aaaUggpd8kfhja1AIJYpx; OUTFOX_SEARCH_USER_ID_NCOO=108436537.92676207; ___rl__test__cookies=1597502296408",    "Host": "fanyi.youdao.com",    "Origin": "http://fanyi.youdao.com",    "Referer": "http://fanyi.youdao.com/",    "user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.125 Safari/537.36",    "X-Requested-With": "XMLHttpRequest",}#提交参数params = {    "i": "I love you",    "from": "UTO",    "to": "AUTO",    "smartresult": "dict",    "client": "fanyideskweb",    "salt": "15975022964104",    "sign": "7b7db70e0d1a786a43a6905c0daec508",    "lts": "1597502296410",    "bv": "9ef72dd6d1b2c04a72be6b706029503a",    "doctype": "json",    "version": "2.1",    "keyfrom": "fanyi.web",    "action": "FY_BY_REALTlME",}url = "http://fanyi.youdao.com/translate_o?smartresult=dict&smartresult=rule"#发起POST请求response = requests.post(url=url,headers=headers,data=params).json()print(response)

    到这里表面上已经完成了有道翻译的代码，但其实还有问题，比如下方如果换了需要翻译的内容就会报错！

原因

    我们在有道翻译重新翻译，会发起新的POST请求，而每次请求所带的参数值会有所不同，如果想要真正实现有道翻译功能，就要找到这四个参数值的生成方式，然后用python 实现同样的功能才行。

3、JS解密(详解)

    Ctrl+Shift+f进行搜索，输入sign

    

因为加密肯定是发起请求的时候加密，所有我们搜索 translate_o

 

   调试

          在有道翻译重新输入翻译内容，即可到断点处停止。

    但是发现数据已经是加密好了的。

    但由于我们是调试模式，可以返回到上一步，点击如下按钮。

  

  可以发现salt、sign、Its、bv都是通过r获取出来的，而r又是通过一个函数得到的。

        进入该函数

    可以发现这里就是加密的地方

    复制这段js代码，我们需要使用python代码来实现。

    可以看到是一模一样的，到这里算是有一点点小成功了。

    注意这里翻译内容不同其bv也是不同的。

接下来看its,用Python实现

  

  可见Python生成的时间戳和JS的有所不同，但细心的小伙伴肯定知道怎么把python的时间戳变成跟JS一样。

    这就ok了！

乘以1000转化为int舍弃小数位再转化为字符串，因为JS里是字符串

      接下来看i,然后用python实现

   

 最后

温馨提示：

    可能会正在有道翻译更新时进行改变，但这不是什么问题，如果仔细看了JS解密的话，还是能够找到新的。
